As a world traveler, Jim, you're better equipped to recognize Nigella. I never heard of it, even from my Indonesian friends. But it apparently has an ancient benefit of some note in subcontinent folk medicine. Might be interesting to try.

Olive oil is great, but has two shortcomings in my case: My wife doesn't use it much to cook (nor do I, but then I don't cook much either). In addition, there is so much criminality in the harvesting of olive oil that I'm never confident of its virginity. In women, who cares? But in olive oil? Gotta be reliably virgin.
